FRANK-K. SINGER, OF PITTSBURGEEIENNSYLV ANIA.

To all whom it may concern:

Be it known that I, FRANK K. SINGER, a citizen of the United States, residing at Pittsburgh, in the county of Alleghen and State of Pennsylvania, have invente new and useful Improvements in Conveying .Machines, of which the following is a specifi cation. a

This invention relates to a machine for successively conveying and dipping articles 1 into baths containing different liquids. As

herein shown and described the invention is used for the purpose of dipping glassware but it will: be understoodv that it is also adapted to be used in-connection with other articles and procemes.

The primary objects of my. invention are to provide a machine of simple/and inexpensive construction whichrwill" automatically act to perform 'a'series of accurately timed operations. Where my invention is used in connection with operations involving uncomfortably high or low temperatures, or dangerous liquids or gases, the whole operation may be erformed within a casing from which the angerous fumes are extracted and expelled fan. a

Other objects of the-invention consisting of novel features of construction will become apparent on reference to the following specification which describes the invention mconnection with 'the accompanying drawings.

In the drawings J Figure 1 is a longitudinal vertical section through the casing of the apparatus.

worms 14 adapted to mesh with worm wheels 15. The worm wheels 15 are secured on transverse shafts 18 which are rotatably mounted in suitable bearings 20 supported on channel beams 21 of the frame-work 10. Crank arms 22, 22' are secured on opposite ends .of the shafts 18 and these arms are displaced 180 apart; In initially placing the arms, however, all of the arms 22 an all of the arms 22" are arranged parallelas, shown in Figure 1. Each of the crank arms are in theform of lamp shades 16 which may be readily suspended from the racks provided by these projecting pins 28. In normal position the rods 26 extend between twochannels 30 which form part of the framework of the apparatus and are arranged parallel and slightly spaced apart so that the rods 26 may just readily pass between them. These channels 30 are suitably supported on the frame work by thelates 31 riveted to the flanges of the channe sand to the side members of the frame 10. The rod 26 at an intermediate point is provldedwith a stop composed of .an angle plate 32 having one arm attached by suitto the rod and the outstanding arm thereof attached to a plug 29 of suitable resilient material, such as rubber. This stop is so positioned relatively to the circular-path traced by the in 23 as torest upon the upper flanges of t e channels 30befor'e the revolvingcrank arms 22, '22 have reached the lower limit of their 'This causes the carrier to be de paths.

posited upon the channel bars until the nextl q rotating arm engages the pocket 25, picks up the carrier and moves it to the nextposition. Suitable receptacles 34, 35 and 36 and 34, 35' and, 36' correspond in location.

to the successive positions of the carriers a they aredeposited on the-channels by the "arms 22, 22'-. These receptacles the articles supported by the carriers are immersed for certain periods of time depending upon the speed of the rotation of the crank arms. The receptacles 34, 35, and 36 are located within a closed casing 37 having openin s 38 and 39 in the end walls through which the carriers may pass in introducing the articles into the casing and removing them from the casing respectively. The upper part of the casing is closed by a cover plate 40 which is provided only with narrow slots 41 for the purpose of permitting the passage of the rods 26 therethrough. In case-liquids, or ases are used which give off dangerous or o ensive fumes, means are provided for exhausting these fumes and ases out of the casing so as to prohibit their escape into the atmosphere of the room where the machine is' operating, and for this purpose the exhaust pipe 42 is used having the exhaust fan 43 mounted therein and rotated by power from any suitable source (not shown). The exhaust pipe 42 is provided with branches 44 and 45 which open into an extension of the outlet opening 39 so that the gases may be drawn off without interfering with the regular operation of removing the carriers from the casing. I y

In order that the operation of my invention may be clearly understood I have indicated the different positions of the carriers by the positions A, B, C, D and E. The

. carriers containing the articles to be treated are first positioned on the channels 30 so that the pocket 25 of the carrier will be in position to be engaged by the button 24 of a crank arm 22. When this occurs the carrier islifted from the channels, passed through the opening 38, and as the rotation of the arm continues the stop 29 encounters the channels 30'at the position B whereupon the articles are suspended in the bath 34. In the mean time, however, the next crank arm has revolved to such position as to pick up the carrier at the position B and transport it to the position C where it is deposited on the channels 30 and the articles are suspended in the receptacle 35. After a short period the next succeedin crank arm engages the carrier and trans ers the same in a circular path until it reaches the position D wherein the carrier is suspended into the receptacle 36;. From this position the crank arm 22 of the last transverse shaft 18 engages the carrier and lifts it through the outlet opening 39 and deposits the carrier on the channels in the position E, from which the same may be removed in any desired manner.

t is believed that from the above description, it is apparent that my device pro-'- vides an apparatus for automatically sub-- mitting articles of glassware or other material to 'a succession of operations all of which table .arms arranged to successively advance a carrier from one location to another, said arms beinginitially arranged in parallel 1 relation and rotating in synchronism so as to provide a simultaneous advancefor all the carriers passing through the machine.

2. In a mechanical conveying ap aratus, a carrier for holding the materia to be treated, a plurality of baths in which the material is adapted to be immersed for definite time intervals, and rotatable arms so arranged as to advance said carrier from one v bath to the other automatically and progressively.

'3. In a mechanical conveying machine, a carrier having a device on the upper end thereof, a series of rotatable arms, means on each of said arms adapted to engage said deviceand advance the carrier from one point to another. A

4. In a machine for dipping articles, a carrier comprising a rod having a pocket at one end, means for supporting the articles at the other end of said rod, and a stop on said rod, a plurality of baths, and means adapted to engage said stop for releasing the carrier from one of said rotating arms and suspending said articles in one of said baths until the next adjacent arm engages said pocket and transfers the carrier to a position corresponding to the succeeding bath.

5. In a machine for dipping wares, a plurality of carriers, a casing containing a plurality of baths and having inlet and outlet openings formed therein, arms adapted to rotate arranged to engage said carriers and I successively advance each carrier from a lbadingpoint outside the casing, through said inlet opening, to the baths successively, and through the outlet opening to the delivery point.
